The mobile application should act as a secretary. So when I choose list of people from my contacts, the software should make an automatic call and play them my prerecorded voice. Let's Say I want to make a personal meeting for 50 people. Generally the secretay should call all of them in person. But this application should call them and play the prerecorded voice, if they understand and received tha voice the call receiver should press 1, if he is unable to come to the meeting he should press 2 and leave voice message. This will help secretary job.
